3 Claims, 4 Drawing Figures ROLLER SKATE TOE STOP ASSEMBLY BACKGROUND OFTHE INVENTION a roller skate which had not been designed so as to acceptit, and secondly, in the case of stopping the roller skate while it wassharply turning, by touching the rubber body to the floor or ground, therubberbody did not touch on the advancing axis of the wheels (they wereturning left or right relative to the body plate), but touched it on thepoint laterally displaced from said axis, because such rubber body wasmounted directly on the body plate, thus resulting in loss in brakeefficiency as well as difficulty in stopping operation.

The present invention has been made in order to eliminate theabove-mentioned disadvantages.

SUMMARY OF THE INVENTION A first object of the present invention is toprovide'a toe stop for a roller skate which has not originallybeenprovided with a toe stop, comprising a pair of holding members on whicha rubber toe stop body is integrally mounted, which is disengageablysecured to a truck provided under the body plate of said roller skate.

A second object of the present invention is to provide a toe stop for aroller skate which is adapted to be mounted on said roller skate withoutparticularly modifying the truck.

A third object of the present invention is to provide a toe stopassembly for a roller skate, which can be integrally mounted on thetruck of said roller skate, thereby being able to turn in the runningdirection of the wheels.

A fourth object of the present invention is to provide a toe stopassembly for a roller skate of which the mounting and removal on and offthe truck of said roller skate is simply made by means of a tighteningbolt penetrating through the bodies of holding members of said assembly.

A fifth object of the present invention is to provide a toe stopassembly for a roller skate which is adapted to be mounted on saidroller skate and tightened by said bolt in such a manner that theembracing arms of said holding members and the gripping arms thereof aresupported by the truck at the wheel axle bearing portion and the rodportion thereof respectively.

A sixth object of the present invention is to provide a toe stop for aroller skate in which said holding members intersect at the forward endsthereof for mounting said rubber toe stop body on the intersectingportion.

BRIEF DESCRIPTION OF THE DRAWING The accompanying drawings show apreferred embodiment according to the present invention, in which:

FIG. 1 is a top plan view showing the essential pa of the preferredembodiment;

FIG. 2 is a bottom plan view showing the same of FIG. 1;

FIG. 3 is a sectional view taken along A A of FIG. 1; and

FIG. 4 is a sectional view taken along B B of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT Description will hereunder bemade with reference to the drawings: In the drawings, the referencenumeral 1 represents a body plate adapted to be secured to the sole of aroller skate shoe (not shown) by an ordinary means. And 2 and 10 are aprotuberance and a bearing bore, respectively, which are provided on ahanger 9 affixed to the underside of the body plate 1 near the front endthereof by rivets or the like. The reference numeral 4 is a wheel axlemounting member, that is, a truck which is secured to the hanger 9 insuch a manner that a rod portion, 11 of the truck is received within thebearing bore 10 and a shock absorbing member 5 is intervened between theprotuberance ,2 and the rearwardly projecting lower end annular flange27 of the truck 4 and through which a tightening screw 6 is inserted.The reference numeral 3 designates a reinforcing plate which issuspended under the body plate 1 with one its ends engaged with thehanger 9 for the forward truck 4 and the other end thereof engaged witha complementary, like hanger (not shown) affixed to the body plate Inear the rear thereof for the rearward truck (not shown) and its middleportion affixed to the underside of the body plate I. 7 is a wheel axlepenetrating through a wheel axle bearing portion 25, on the both ends ofwhich are rotatably mounted wheels 8 via bearings. 16 and 17 represent apair of holding members which constitute the main feature of thisinvention. These holding members 16 and 17 are each integrally formedwith respective embracing arms 20 and 21 adapted to embrace the bearingportion 25 from' below, and gripping arms 18 and 19 for gripping the rodportion :from both sides, respectively. These holding members 16 and I7intersect at the forward ends thereof, forming an intersecting portion22 through which a tightening screw26 is screwed. 24 is a tighteningbolt penetrating through a boreformed in the bodies of the holdingmembers 16 and 17 for preventing the opening of the holding members 16and 17 about the tightening screw 26, by which bolt the securement ofthe holding members 16 and 17 to the truck 4 is maintained. 23 is arubber toe stop body secured to the intersecting portion 22 of theholding members 16 and 17 by the tightening screw 26. 12 is an arcuatesurface formed on the outer surface of the rod portion, and 14 and 15are shoulders formed on the reverse side of the arcuate surface andextending along the length of the rod portion 11 between which isintervened a ridge 13 also extending along the length of the rodportion. The

-interiors of the aforementioned gripping arms are shaped so as tocomplementarily engage with the soconfigured exterior of the rod portion11.

In the drawings, the holding members 16 and 17 are shown in engagementwith the rod portion 11. To disengage these holding members from the rodportion, you have only to unscrew the tightening bolt 24 and rotate theholding members 16 and 17 away from one another about the tighteningscrew 26. Then, the holding members 16 and 17 will be detached from therod portion and at the same time the embracing arms 20 and 21 will getseparated from the bearing portion 25. Thus, the whole toe stop assemblyis disengaged from the roller skate. Reversely, in order to mount thetoe stop assembly on the roller skate, you have only to place theembracing arms 20 and 21 in contact with the underside of the bearingportion 25, grip the rod portion 11 with the gripping arms 18 and 19,and then screw the tightening bolt 24 through the bore.

Since a toe stop assembly according to this invention has a constructionas described in the foregoing, it will be clearly understood that thistoe stop assembly is mountable on any roller skate without a toe stop ingeneral. Further, this invention has another advantage that this toestop assembly does not necessitate any modifications to the roller skatein mounting the toe stop on the roller skate. Still further, accordingto this invention, since the toe stop rubber body 23 is fixed to thetruck 4 via the holding members 16 and 17 it always turns left and rightwith the wheels 8 and exactly turns in the turning direction of thewheels 8 so that it touches the ground on the advancing axis of thewheels 8, thus exhibiting a strong braking function as well as anexcellent maneuverability. Further, this toe stop assembly has a verysimple construction enough to be mountable onto a roller skate just bymeans of a tightening bolt.
